Pineda, Director Prepared by Robert D. Zuber Environmental Protection Specialist September 10, 2010 INTRODUCTION This document is the proposed decision of the Colorado Division of Reclamation, Mining and Safety(the Division)in response to a request for Phase II bond release for a portion of the Keenesburg Strip Mine, Division permit number C-1981-028. The Division file number for the bond release application is SL-05. The application was submitted to the Division on February 19,2010 (date of receipt by the Division). After receipt of proof of publication of a public notice in a newspaper of local distribution near the mine (Rule 3.03.2(1)(b)), the application was deemed complete on April 12, 2010. The bond release inspection was conducted on April 22, 2010. The package contains four parts. These include: 1)procedures and summary of the bond reduction and bond release processes; 2) criteria and schedule for bond release; 3)observations and findings of the Division regarding compliance with the bond release requirements of the Colorado Surface Coal Mining and Reclamation Act and regulations promulgated thereunder; 4)the Division's proposed decision on the request for bond release. Detailed information about the review process can be found in the Act and the Regulations of the Colorado Mined Land Reclamation Board for Coal Mining. All Rules referenced within this document are contained within the Regulations. Detailed information about the mining and reclamation operations can be found in the permit application on file at the Division offices, located at 1313 Sherman Street, Room 215, in Denver, Colorado. The Keenesburg Strip Mine is a surface mine which is permitted and operated by Coors Energy Company. The Keenesburg Strip Mine permit area covers approximately 612.50 acres. The total approved disturbed area is 439.00 acres. The bond release area consists of eleven parcels (parcels 2, 5, 6, 7, 9, 10, 15, 16, 19, 23, and 29)totaling 51.05 acres. The ownership of the land for which bond release has been requested is private. The coal mined from the requested area was owned privately and by the State of Colorado. Reclamation for which bond release has been requested was completed for the given parcels in 1995, 1998, 1999, 2002, and 2003. C1981-028, SL-05 2 9/10/2010 PROCEDURES AND SUMMARY OF THE REVIEW PROCESS Coors Energy Company applied for a bond release(Phase II) on a portion of the Keenesburg Strip Mine, consisting of 51.05 acres, that has been reclaimed in accordance with the Colorado Surface Coal Mining and Reclamation Act. The mine is located in Weld County, in all or portions of Sections 2 and 11,T2N, R64W; and Sections 25 and 36,T3N,R64W; 6th Principal Meridian. Coors Energy Company(CEC)has previously requested and been approved for four bond releases. Bond release SL1 was approved on August 11, 1998 for Phase Ion 179 acres and Phase II on 111 acres. Bond release SL1 released $1,787,113.00 of the reclamation liability. A second bond release, SL2, was approved August 31, 2005. Bond release SL2 approved Phase I release on 51.76 acres. The Division approved$287,918.00 for release from the reclamation liability for ten(10)reclamation parcels included in the request. A third bond release application, SL3, was approved on April 18, 2006. Bond release SL3 was a Phase II bond release 53.90 acres. The Division approved the release of$130,189.80 of the reclamation liability for Phase II bond release on ten (10)reclamation parcels. A fourth bond release application, SL4, was approved on January 8, 2010. Bond release SL4 was a Phase III bond release of 165.29 acres. The Division approved the release of$167,911.00 of the reclamation liability for bond release on 17 reclamation parcels. The Division received CEC's application for a Phase II bond release(SL-05) on a 51.05-acre portion of the reclaimed area on February 19, 2010. Following four consecutive weeks of publication of the public notice in the Fort Lupton Press, the application was deemed complete on April 12, 2010. CEC also notified landowners within and adjacent to the mine permit area and other interested parties of the application for bond release as required by Rule 3.03.2O). No comments, written objections, or requests for an informal conference regarding the bond release application were received by the Division. The Division conducted a bond release inspection on April 22, 2010. The site inspection was conducted in accordance with Rule 3.03.2(2). Persons at the bond release inspection included Mr. Don MacDonald and Mr. Danny Kipp, representing Coors Energy Company(CEC); Robert Zuber, Dan Hernandez, and Janet Binns of the Colorado Division of Reclamation, Mining and Safety; Christine Belka of the Office of Surface Mining, Reclamation and Enforcement(OSM); and Mike Savage, of Savage and Savage, a CEC consultant. The surface ownership of the property included in the bond release area is privately owned by CEC. The Colorado Department of Public Health and Environment, Hazardous Materials and Waste Management Division, Solid Waste Unit (CDPHE-SWU)was notified of the SL-05 bond release application by mail and by telephone. Ms. Cindy Smith of CDPHE-SWU stated in a phone conversation on March 30, 2010 that representatives of the Solid Waste Unit did not need to inspect the bond release areas at the Keenesburg Mine prior to the Division's proposed decision. The Weld County Department of Public Health and Environment was also notified of the SL-05 C1981-028, SL-05 3 9/10/2010 bond release application by mail and by telephone. During a telephone conversation(in March 2010)with Mr. Troy Swain of the Weld County Department of Public Health and Environment, Solid Waste Division, Mr. Swain stated that he would like to attend the SL-05 bond release inspection,but it was not necessary for him to attend. He did not attend the inspection. A representative of the Colorado Board of Land Commissioners, Mr. Mark Davis, was notified in advance of the inspection by mail and by telephone; however, no one from his agency attended the inspection. During review of the bond release application, the Division identified four issues with the analysis performed by CEC's consultant: • In the 2009 Vegetation Monitoring report, the area in Table 3 was misidentified as Area 29; it is actually Area 30. • In the 2009 Vegetation Monitoring report, it was not clear that the sampling for Area 23 was sufficient. • In the Sedimentology Demonstration,one of the transects used in the adjacent undisturbed area analysis (the southern transect, A-A') should not have been used because the adjacent undisturbed area is no longer undeveloped. • In the Sedimentology Demonstration, the Length Slope(LS) factor for one of the transects used in the adjacent undisturbed area analysis was incorrectly calculated per the equation given in the application. CEC's consultant made the recommended changes in the respective reports. II. CRITERIA AND SCHEDULE FOR BOND RELEASE PHASE I Rule 3.03.1(2)(a) states, "Up to sixty percent of the applicable bond amount shall be released when the permittee successfully completes backfilling, regrading, and drainage control in accordance with the approved reclamation plan." With regard to Phase I bond release, the approved reclamation plan for the Keenesburg Strip Mine calls for backfilling mine pits to the approximate original contour (permit page 113). All parcels included in SL-05 have previously received Phase I bond release approval. PHASE II Rule 3.03.1(2)(b) states, "Up to eighty-five percent of the applicable bond amount shall be released upon the establishment of vegetation which supports the approved postmining land use and which meets the approved success standard for cover... based on statistically valid data collected during a single year of the liability period." In regard to Phase II bond release, Rule 3.03.1(3)(b) also states, "No more than sixty(60) percent of the bond shall be released so long as the lands to which the release would be applicable are contributing suspended solids to streamflow or runoff outside the permit area in excess of pre-mining levels as determined by baseline data or in excess of levels C1981-028, SL-05 4 9/10/2010 determined on adjacent non-mined areas." The approved reclamation plan is found in Section 2.05.4 of the permit application. The required topsoil replacement thickness is two (2) feet. The approved post-mining land use is rangeland. The Dugout Pond,perimeter ditches, and Pond 2 have been approved to remain as permanent structures. III. OBSERVATIONS AND FINDINGS Revegetation The Keenesburg Mine permit previously utilized comparison of an approved reference area,known as the Osgood reference area, for revegetation success of the reclaimed areas. Comparison to the Osgood reference area was not ideal due to a successional change of the species composition in the reference area to a community heavily dominated by sand sagebrush and a reduction of forage grasses and forb species over the years. Also, a change in surface ownership of the property upon which the reference area was located caused concerns regarding management of the reference area. CEC proposed revegetation success standards for vegetative cover and herbaceous productivity based on a formula derived from historic data collected on the Osgood reference area and a correlation to precipitation records(TR37, approved June 15, 2006). Permit page 2.05.4-116b defines the required cover standard for the Keenesburg Strip Mine. The permit states, "Reclaimed areas will be considered successfully reclaimed if the total vegetative cover on the reclaimed area is not less than 90 percent of the predicted calculated cover value with 90 percent statistical confidence using the equation: y=0.0173x3-0.8592x2 + 14.562x-47.015, where xis the cumulative value of precipitation from September to July of the following year, and y is the resultant vegetation cover." This cover standard is in agreement with Rule 4.15.8. The calculated cover standard for 2009 is 35.7 percent live vegetative cover, based on 13.71 inches of measured precipitation for the preceding September to July. CEC reported in the 2009 vegetation sampling report that the overall vegetative cover for reclaimed areas seeded in 1998, 1999, and 2000 (reclamation areas 2, 5, 6, 7, 9, 10, 15, 16 and 19) was 60.96% live vegetative cover. However, per Rule 4.15.1(2) and the Division's 1995 Bond Release Guidelines, noxious species cannot contribute to reclamation success. Table 2 in CEC's revegetation report shows that Bromus tectorum (cheatgrass) contributed 8.3%to the live vegetative cover(LVC)on this Bond Release Block(BRB), and this amount must be removed from the value of 60.96%for a sub-total of 52.66% LVC. Furthermore, in measuring reclamation success the allowable cover contribution of annual and biennial species should not exceed 10 percent(based on Division policy and the Division's 1995 guidelines). Of the 36 plant species sampled on the 1998/1999/2000 BRB, 14 species were determined to be annual or biennial. The 14 annual and biennial species contributed 13.19%of the total cover and 28.67% of the relative cover(from Table 2). To limit the relative cover of annual and biennial species to exactly 10 percent, a portion of these species were removed from a revised Table 2, and the resulting LVC is 44.07%. C1981-028, SL-05 5 9/10/2010 • Thus, the live vegetative cover measured on the 1998/1999/2000 BRB (44.07%) exceeds the calculated cover standard(35.7%) and is considered successful for the 2009 sample year. In addition, this BRB was sampled to statistical adequacy. CEC also submitted data from a second BRB (BRB 2002/2003) representing a logical management unit (LMU) composed of reclamation parcel 23 and reclamation parcel 29. Parcel 23 was seeded in 2002, and parcel 29 was seeded in 2003. The same seed mix was used on both parcels, and both parcels are located in close proximity to one another. The Division accepts combining the data from these two parcels as an LMU. Removal of cover attributed to noxious species (Cheatgrass) and removal of annual and biennial vegetative cover in excess of 10%results in 46%LVC for parcel 23 and parcel 29 data, which is greater than the cover standard of 35.69% LVC, and BRB 2002/2003 meets the reclamation success standard for cover. In addition, BRB 2002/2003 (parcel 23 and parcel 29) was sampled to statistical adequacy. Water Quality Impacts The operator submits a surface and groundwater report to the Division annually. The Division's review of the annual hydrology reports concludes that the areas under consideration for bond release are not contributing suspended solids to streamflow or runoff outside the permit area in excess of pre-mining conditions. Sediment pond No. 2 and the dugout pond at the Keenesburg Strip Mine have not discharged in many years. Both sediment pond No. 2 and the dugout pond were previously approved to remain as permanent structures (TR32 and TR28). The Division determined during previous Phase II bond release reviews that runoff from the bond release areas were not contributing additional suspended solids outside of the permit area. The Division finds that there have been no adverse effects to groundwater down gradient of the permit area. The Division concluded the Keenesburg Mine does not have the potential to negatively impact ground water and has not required establishment of a groundwater point of compliance (Memo to 2004 AHR file, dated July 6, 2005). If coal spoil leachate or ash leachate migrated from the pit through eolian sand, Ennis alluvium or the Laramie sandstone, coal attenuation and dispersion would result in levels of total dissolved solids (TDS) and sodium adsorption ratio (SAR) in ground water that would be near pre-mining conditions within a few hundred feet of the Keenesburg Mine pits. Monitoring of groundwater quality in the down- gradient wells from the reclaimed pits found the 2008 TDS values were well below the pre- mining levels. The Probable Hydrologic Consequences section of the permit application predicts no appreciable impacts to the hydrologic balance. Monitoring data in the hydrology reports confirm this prediction. No impacts to groundwater have been found in down gradient groundwater monitoring wells. Based upon this information as well as the Sedimentology Demonstration submitted with SL5, the Division finds that with regard to bond release application SL5, pollution of surface water and subsurface water is not occurring and the probability of such pollution occurring is low. C1981-028, SL-05 6 9/10/2010 IV. PROPOSED DECISION Based on the observations above,the Division proposes to approve Coors Energy Company's request for a Phase II bond release for the Keenesburg Strip Mine. This proposed decision will release the applicant from a portion of the liability in accordance with Rule 3.03.1(2)(b). The Phase II bond release applies to 51.05 acres consisting of parcels 2, 5, 6, 7, 9, 10, 15, 16, 19, 23, and 29. The Division in SL-03 redefined the original bond amount of$4,402,022.00 to be the"applicable bond amount" for determining bond release, with no subtraction of structural demolition costs prior to calculating Phase UI11111 liability release values. In SL-05, Coors Energy Company has requested a bond release of$179,646.00. However,the Division has estimated the cost to complete remaining reclamation tasks and maintenance following the proposed approval of SL-05 to be$2,001,475.00 (see Appendix A). Rule 3.03.1(3)(d) requires that adequate bond be retained to allow the Division to conduct any remaining reclamation tasks in the event that the Division takes over the permit. Based on the Division's estimate of remaining liability and the Division's observations of reclamation success,the Division proposes to release $120,385.00 (costs associated with Phase II revegetation and topsoil replacement tasks)of Phase II reclamation liability. The remaining bond of$2,001,475.00 shall be sufficient to assure completion of the remaining reclamation work at the site if the work had to be performed by the Division, including the cost of reestablishing vegetation on any revegetated areas should those areas fail. The following table summarizes the history of liability at the Keenesburg Mine.

Details of the Keenesburg Mine's reclamation plan may be found in Section 2.05.4 (p. 113) of the permit. Pond 2,the Dugout Pond, and the East and West perimeter diversion ditches are approved to remain permanently. Any person with a valid legal interest which might be adversely affected by this proposed decision may request a formal public hearing before the Mined Land Reclamation Board in accordance with Rule 3.03.2(6). Public notice of this proposed decision will be published once per week for two weeks in the Fort Lupton Press as soon as possible. Requests for public hearing must be submitted to the Division in writing within thirty days of the first publication in the Fort Lupton Press. If no hearing is requested within thirty days, the Division's proposed decision will become final.
